There have been some glitches with the HVAC system at Danbury High School. Public Works Director Antonio Iadarola says they lost a few compressors in the new wing.  This is the first long year for the newly expanded and renovated building to have full capacity because of the timing with remote learning during the pandemic. He notes that means the system hasn't been pushed to its limits until now.  While what he's seeing is a little concerning, they're working through it.  The City has an on-call contractor that monitors that system and they're meeting to figure out what the issue is--whether it's a design issue, an operational issue, or something else.  Iadarola says there's an intricate computer system that monitors every aspect of HVAC systems in a school, and so far they've found that some of the communication links between the computer system and the devices that tell them what's going on in a building were not talking with each other.
